Description
実験で使用する分散剤を下記の表にまとめる。
エポキシ分散体1、および3〜5は、KWP(Krupp Werner & Pfleiderer社)ZSK25押出機(25mmスクリュー径、60L/D、450rpmで回転)を使用して、下記の手順に従って、下の表1〜4で報告される各水性分散体での調合成分で調製した。固体エポキシ樹脂および半結晶性PVOHポリマーをSchenck Mechatronロス・イン・ウェイト・フィーダを介して押出機の供給口へ供給後、溶融ブレンドし、次に初期水流存在下で乳化した。いくつかの場合においては、実施例4に示されるエポキシブレンド分散体で、液体エポキシ樹脂流を溶融区域に注入して、乳化区域に入る前に固体エポキシ樹脂および半結晶性PVOHと溶融ブレンドした。次にエマルション相を前方の押出機の希釈および冷却区域へと前方に運搬し、ここでさらなる水を添加して、70重量パーセント未満の固体レベル含有量を有する水性分散体を形成した。初期水、および希釈水を全て、ISCO2重シリンジポンプ(500mL)により供給した。押出機のバレル温度は110℃に設定した。分散体が押出機を出た後、分散体をさらに冷却し、200μmメッシュサイズの袋ろ過器を通してろ過した。
数種のエポキシ樹脂分散体を調製し、表2にまとめた。最小粒径およびそれに対応するHIPE中の固体含有量を表に示す。POVAL(商標)PVA205はPVOHの細かい顆粒等級であり、化学性質に関してはMowiol(商標)488と非常に類似している。同じ量のPVOHで、0.43μmのより小さい粒径(表1の分散体1と比較して)が得られた。換言すれば、固体顆粒のより小さい粒径により、POVAL(商標)PVA205はMowiol(商標)488よりも、より効果的である。さらに、7%の少ないPOVAL(商標)PVA205を使用して、エポキシ分散体を調製することができる。
表3において、最小粒径を達成するために必要なHIPE中のIAは、PVOHの分子量にも依存し、換言すれば、分散剤として高分子量PVOHは乳化区域においてより多くの水を必要とする。再び、細かい粉末等級PVOH(MOWIOL(商標)2388G2)は分散体中でより小さいエポキシ粒子を作製した。
エポキシブレンド分散体も、押出成形機をベースにした分散方法により調製した。この方法において記述した通り、液体エポキシを押出成形機に注入して、固体エポキシおよび半結晶性Mowiol(商標)488とその場で(in situ)溶融ブレンドし、その後乳化した。
